I tried installing 4 different IS215UCVEH2A cards in my R rack and each time I try to ping the IP address through the cmd promt I get an error 'Request Timed Out'. I thought that the problem may be with the compact flash card, but I used 6 different flash cards. I then powered down the rack, took out the UCVE card and measured the battery voltage. 3 cards read 0 and one read 2.7. The fact is these cards had a voltage of 2.9V. My question is if anybody here knows why the battery is draining charge? Has anybody faced a similar situation earlier? The S and T cores are working perfectly.

and hit Enter.

Some tips for better search results...

Precede each search term with a "+", as follows:

+Modbus +TCP

Otherwise, any post with either term will match.

Use double quotes around phrases, as follows:

+"Allen Bradley" +ethernet

Otherwise, posts containing these words in separate locations will match.

To exclude a word, precede it with a "-", as follows:

+Modbus -Plus

This will return only posts containing "Modbus" but NOT containing
"Plus".

Note that common words (and, that, etc.) and words shorter than 2 characters
are automatically excluded from searches.
